The dark antinyms, whose identity was stolen as the universal market of their True Self was stretched thin, shifting the very name of their being, warping their reality and making them crave the simple ritualistic interactions. They lie in wait, occasionally wearing a good enough mask to politely say, "May I have your name?"

Or, really, namesake, honoree, entonym, as all these others have helpfully said. Usually it's just 'which x was named for', I think, one of those quirks.

@cstross
I found this after thinking "in Dutch we have naamgever (name giver), naamlener (name lender), and naampatroon (name patron).

@cstross It could be "eponymist."

@cstross Isn't that "namesake"?

@cstross
In German it's Namenspatron, in case you wondered 🙃

@cstross Namesake or eponym?

@cstross
Naval formal and also public informally 'namesake', linguistically the ship is the 'eponym', the person is the 'eponymous name', ceremonial 'honorand'. Legal might be 'dedicatee'.

@cstross Generally, "eponym" or "namesake".

@cstross

Boat ship or fictional relationship ship?
